Actually, the Lotus 2.01 AT&T 6300 driver gives you 50 lines.
Turbo Reflex also knows about the AT&T high resolution mode.


Anyway, according to the Xerox 606x Operator's Guide, if you have
ansi.sys installed, the following escape sequence will switch to 50
line mode  (see appendix J, page 12):

SM - Set Mode
-------------

	Esc [ = Ps h
or	Esc [ = h
or	Esc [ = 0 h
or	Esc [ = ? 7 h

The SM escape sequence changes the screen width
or type to one of the following:

Parameter	Function
---------	--------
  0		40 * 25 black & white
  1		40 * 25 color
  2		80 * 25 black & white
  3		80 * 25 color

  4		320 * 200 color graphic
  5		320 * 200 black & white graphic
  6		640 * 200 black & white graphic
  7		wrap at end of line

 64		set 640 * 400 graphic mode with
		80 * 25 character set
 72		set 640 * 400 graphic mode with
		80 * 50 character set


In the definition, Ps is a metacharacter for the ascii value(s) for
the paramers in the list above.  For 50 lines, you'd send ascii "7"
and ascii "2" to the console driver.

Use the following GWBASIC program to make a text file that you can
TYPE to the console to set the mode:

10 OPEN "SETMODE.50" FOR OUTPUT AS #1
20 PRINT #1, CHR$(27)"[=72h";
30 CLOSE

Remember, you need to include the line "DEVICE=ANSI.SYS" in your
CONFIG.SYS file on your boot disk.  Obviously, a copy of ANSI.SYS
also needs to be on your boot disk.


I tried the above on the Xerox 6065, which is the same hardware and
virtually the same software expect for Xerox's screen mate (gak!)
as the PC6300.  I would have tried it on my own PC6300, but I am
using an EGA card in place of the indigenous video board.

Several of the P/D or shareware replacements for ANSI.SYS (Fansi
Console for instance) offer support for AT&T 50 line mode.
Unfortunately, getting applications software to realize you have
more than 25 lines isn't so easy...

Last of all, the 50 line mode is ONLY black & white, unless you
have one of the elusive DEB boards.
